–  Phase 1 healthy adult trial data of EDG-15400 and plans for heart failure studies expected in H1 2026  –

–  Pivotal GRAND CANYON results for sevasemten in Becker muscular dystrophy (Becker) expected in Q4 2026  –

BOULDER, Colo., Feb. 26, 2026 /PRNewswire/ — Edgewise Therapeutics, Inc. (Nasdaq: EWTX), a leading muscle disease biopharmaceutical company, today reported financial results for the fourth quarter and full year of 2025 and recent business highlights.

“Following strong execution in 2025, we have entered a transformative year,” said Kevin Koch, Ph.D., President and Chief Executive Officer of Edgewise. “We remain on track to deliver pivotal GRAND CANYON top-line data for sevasemten, with the potential to support the first marketing application for the treatment of Becker. We also expect CIRRUS-HCM 12-week Part D results for EDG-7500 in HCM in the first half of 2026. Data from Part D will support refinement of our Phase 3 trial strategy in HCM. With multiple near-term catalysts and a high-performing team, we are closer than ever to delivering transformative medicines for patients living with serious conditions that still lack adequate treatment options and represent significant unmet medical needs.”

Recent Highlights

Muscular Dystrophy Program

GRAND CANYON, a global pivotal placebo-controlled cohort in Becker: GRAND CANYON is designed to assess the efficacy and safety of sevasemten over an 18-month period, with North Star Ambulatory Assessment (NSAA) as the primary endpoint. The study is highly powered to be able to show a statistically significant difference in NSAA versus placebo over 18 months. The Company expects to report top-line data in the fourth quarter of 2026 and is continuing preparations for a potential NDA submission to the U.S. Food and Drug Administration (FDA) for sevasemten in Becker, planned for the first half of 2027. To learn more about GRAND CANYON, go to clinicaltrials.gov (NCT05291091).

MESA open-label extension trial in adults with Becker: The Company continues to advance MESA, an open-label extension trial that collects long-term safety and efficacy data of sevasemten in participants with Becker who were previously enrolled in ARCH, or who completed CANYON, GRAND CANYON, or DUNE. As of December 2025, 99% of eligible participants have enrolled in MESA, with exposures to sevasemten for up to four years.

LYNX and FOX Phase 2 placebo-controlled trials in boys with Duchenne: LYNX is designed to evaluate the effect of sevasemten on safety, biomarkers of muscle damage and function in 4- to 9-year-old participants with Duchenne in a placebo-controlled dose ranging study, followed by an open-label extension period. FOX is designed to evaluate the effect of sevasemten on safety, biomarkers of muscle damage and function in 6- to 14-year-old participants with Duchenne who have been previously treated with gene therapy. The Company will continue to collect longer-term safety and functional data in the open-label extensions of LYNX and FOX while it plans for a Phase 3 program. For more information, go to clinicaltrials.gov to learn more about LYNX (NCT05540860) and FOX (NCT06100887). 

Cardiovascular Programs

CIRRUS-HCM Phase 2 trial in adults with symptomatic HCM: The Company is advancing CIRRUS-HCM, a multi-part, open-label trial, in participants with HCM at over 20 clinical sites in the U.S. Part A of the trial evaluated the safety and tolerability of a single oral dose of EDG-7500 in participants with obstructive HCM (oHCM). Parts B and C evaluated fixed doses of EDG-7500 over 28 days in oHCM and nonobstructive HCM (nHCM), respectively. Part D is a 12-week study with an open-label extension including participants with oHCM and nHCM designed to explore dose response and optimization. The Company plans to report 12-week Part D data in oHCM and nHCM in the first half of 2026 and initiate Phase 3 in the second half of 2026. To learn more about CIRRUS-HCM, visit clinicaltrials.gov, NCT06347159.

EDG-15400 and heart failure: EDG-15400 is a novel oral, selective, cardiac sarcomere modulator, targeted for the treatment of heart failure and other diseases of diastolic dysfunction. EDG-15400 is currently being evaluated in healthy adults in a Phase 1, randomized, double-blind, placebo-controlled, single and multiple ascending dose study evaluating safety, tolerability, pharmacokinetics and pharmacodynamics. The Company expects top-line results from this study in the first half of 2026 and to initiate a Phase 2 trial in participants with heart failure with preserved ejection fraction (HFpEF) in the second half of 2026. To learn more about this study, go to clinicaltrials.gov (NCT07177066).

Fourth Quarter Financial Results

Cash, cash equivalents and marketable securities were approximately $530.1 million as of December 31, 2025.

Research and development (R&D) expenses were $43.6 million for the fourth quarter of 2025, compared to $37.5 million for the immediately preceding quarter. The increase of $6.1 million was primarily driven by a $3.5 million increase in personnel related costs, $2.2 million increase in EDG-15400 clinical development activities related to Phase 1 trial activity initiated in the third quarter 2025, a $1.9 million increase in EDG-7500 clinical development activities related to continued patient activity in our CIRRUS-HCM trial and other pharmacokinetic studies, partially offset by a $0.8 million decrease in sevasemten clinical development activities related to decreased patient activity in GRAND CANYON as patients transition to the MESA open-label extension trial and a $0.7 million decrease in professional fees, manufacturing, and other research costs.

General and administrative (G&A) expenses were $12.4 million for the fourth quarter of 2025, compared to $9.4 million for the immediately preceding quarter. The increase of $3.0 million was primarily driven by a $2.2 million increase in personnel-related costs and a $0.8 million increase in professional fees and other administrative costs. 

Net loss and net loss per share for the fourth quarter of 2025 was $50.2 million or $0.47 per share, compared to $40.7 million or $0.39 per share for the immediately preceding quarter.
